Aaron Barnea and his wife were watching television on Yom HaShoah (Holocaust Memorial Day) last year when there was a knock at the door. He opened it to find what Barnea called "the picture that every Israeli knows and hopes never to see." Two men in Israel Defense Force uniforms had come to deliver the news Barnea knew instantly when he saw them: His son Noam, 21, had been killed by Hezbollah in Lebanon. He had just five days to go in his mandatory army service. Noam had always been a peace activist, Barnea recalled, and strongly opposed Israel's ongoing presence in Lebanon. His superiors reprimanded him for wearing a "Leave Lebanon in Peace" button while serving there, but he refused to remove it. That button was returned to the Barnea family with the rest of Noam's things upon his death.
